Application December 22, 1932, Serial No. 648,426 Renewed February 26, 1934 16 Claims. (01. res-7.1)

My invention relates toa collapsible shelter for use on beaches or the like in which a. rib or bowed structure with fabric stretched between the ribs or bows may be opened or extended to form a shelter which may be folded or collapsed for carrying to and from the place of use.

In this type of shelter an object and feature of my invention is a construction by which. the shelter may be supported and stretched between a pair of posts or stakes separated apart by the length of the shelter and in which the shelter may be adjusted vertically on the posts.

A further object and feature of my invention is forming the shelter witha plurality of bows or ribs, the ends of the bows being pivotally connected to adjustable clamps which may be placed at any desired elevation on the stakes.

A further feature of my invention is the employment of a readily engageable and disengageable spring which may be used to extend the bows apart so that the fabric covering between the bows forms a shelter. By this construction therefore the ends of the bows converge .to the pivot when the shelter is extended and thus the pivot ends may be readily attached to the clamps.

Another detail feature of my invention relates to the combinational clamps and hub structure by which the ends of the bows are secured in a socket My invention is illustrated in connection with r the accompanying drawing, in which Fig. 1 is a side elevation taken in the direction of the arrow I in Fig. 2.

Fig. 2 is a front elevation taken in the direction of the arrow 2 of Fig. 1.

Fig. 3 is a vertical section on the line 3-3-0! Fig. 1 or Fig. 4, in the direction of the arrows.

Fig. 4 is a horizontal section on the line 44 of Fig. 3, in the direction of the arrows.

Fig. 5 is a vertical detail section on the line 5-5 of Fig. 3 in the direction of the arrows. Fig. 6 is a partial elevation illustrating the attachment of the spring to one edge of the shelter. As illustrated, the shelter has end ribs or bows H and intermediate ribs or bows l2, these being arched. Each of the bows has opposite outwardly bent ends l3. Between the bows there is a fabric covering [4, and this fabric is so shaped that the ends of the bows fit close together.

A housing for the bows comprises a hub structure l5 which has a cylindrical section IS with a bent-in flange I1 and an outwardly extending disc l8. This disc at the lower portion has a flange I9. Inside the cylindrical section there are a pair of shoulders 20 and resting on these shoulders there is an arcuate plate 2| having straight ends 22, these latter fitting on the 5 shoulders 20. This construction therefore forms an arcuate socket 23 in which the outwardlybent arm 30 parallel thereto.. Each of these arms is provided with a perforation 3| through which extends the shank 32 of a bolt, the head 33'of which fits against the short arm 29. The inwardly turned flange l'l provides an opening through 20 which extends'the shank 32 of the bolt, and on this bolt there is a disc 34 which has an outwardly flared edge 35. A thumb operated nut 36 is threaded on the shank of the bolt and bears against the disc 34, thus through the medium 25.

of the head 33 exerting a clamping action on the arms 29 and 30 and the circularsection 28 of the clamp. This action of tightening the clamp also secures the section 36 of the bows adjacent their ends between the arm 30 and the disc-like 30 the hub, and these normally may be at a considerably obtuse angle one to the other or they may be in alignment. Each arm has a hook 4| which I may be fitted in a grommet 31. Thus, one of the 45 hooks 4| may be fitted in one of the grommets, the base may be spread apart by hand and the opposite arm bent from the full line position of Fig. 5 to the dotted line position, or from the dotted to the full line position of Fig. 1, and thus 50 hold the bows and the fabric cover'spread or extended. As shown in Fig. 1, the shelter forms an arc of slightly more than ninety degrees. Maniiestly this may be changed to be either more or less. 63

From the above description it will be seen that the shelter is readily assembled, the ends of the bows being readily insertablein-the sockets attached to the hubs, which hubs are used to tighten the clamps on the stakes. Therefore, the height of the shelter above the ground line may be readily changed within the limits of the stakes, and on account of the springs at each end coiled around each hub and having the two arms the shelter is always held in an extended position when in use. If desired the thumb nut may be clamped sufficiently tight to secure the portions 36 of the hubs or bows between the plate 30 and the disc. l8 suiiiciently tight so that the shelter is held or maintained in the desired extended position without necessitating spreading the shelter by means of the spring 38.

Various changes may be made in the principles of my invention without departing from the spirit thereof, as set forth in the description, drawing and claims.

I claim:

1. A shelter comprising in combination a pair of stakes, a plurality of bows having fabric thereon, a clamp for each stake, a pivot structure connected to each clamp'for pivoting the ends of the bows whereby the bows may be collapsed or folded or extended, the tightening of the clamp retaining the pivoted ends of the bows in adjusted position.

2. A shelter as claimed in claim 1, and means to extend the bows comprising a spring engaging a plurality of bows and tensioned to force said bows apart.

I 3. A shelter comprising in combination a pair of stakes, a clamp for each stake, a hub structure attached to each clamp, each'hub structure having a pivot means forengaging the ends of a plurality of b'ows whereby the bows may be collapsed or folded together, or spread apart, said bows having a fabric cover.

4. A shelter as claimed in ,claim 3, and a means .to extend the bows comprising a spring fitted 'on at least one of the hubs and having means to engage at least two bows and tensioned to force said bows .into extended position.

5. A shelter comprising in combination a pair of stakes, a clamp secured to each stake, a hollow hub structure secured to each clamp, each hub structure having a socket, a plurality of bows having fabric therebetween, each bow having its opposite ends fitting in a socket.

6. A shelter as claimed in claim 5, and a means to extend the bows comprising a spring coiled on each hub structure, each spring having an arm; and means to engage the free ends of the arms with the two extreme bows.

'7. A shelter comprising in combination a pair ,of stakes, a clamp for each stake having a bolt,

a hollow hub structure mounted on each bolt,

each hub structure having a socket, a plurality of bows having fabric therebetween, the ends of each bow fitting in a socket, and a nut on each bolt to tighten the hub on the clamp and secure each clamp to a stake.
